In the drawports, and the water flowing past the va'flve ings I have shown three of these channels will pass out through the top of the chamber extending from the valve-seat to the top of without entering the ports or forcing out the I00 sectional packing during the descent of the plunger. The upper end of the piston is provided with an annular groove or recess, and the reduced end portion 15 formed thereby is threaded to receive an interiorly-threaded ring 16, that is formed integrally with a bridge or yoke 17 and constitutes therewith the bail or handle of the bucket or piston. When the ring and yoke are cast, being preferably formed in that way, the guiding-rod 9 is placed in the mold and the yoke cast. around it. The upperend of theguiding-rod is threaded, as shown, to permit its convenient attachment to a pump-rod. The yoke and guidingrod may be removed at any time from the piston to permit access to the valve or its seat.

The construction described above permits me to produce a very compact and durable bucket or piston, and the relative positions of the valve and Water-ports renders the packing particularly efficient to prevent leakage around the piston.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The combination with a pump-piston having a chamber provided with a water-outlet opening and an unobstructed inlet-opening, ofa guide-rod, a vertically-movable valve adapted to close said inlet-opening and telescope with the said guide-rod to present the unobstructed inlet-opening to the free passage of water, said chamber being provided with water-channels extending above and below the limit of the upstroke of said valve to present a cross-sectional area around the edge of the valve for the free flow of Water entering the unobstructed inlet-opening.

2. A pump-bucket, comprising a cylinder having a chamber provided with unobstructed inlet and outlet openings, a guide-rod depending within said chamber above the inletopening, a valve vertically movable within the walls of said cylinder and normally closing the inlet-opening, said valve having a hollow upwardly-projecting stem to telescope with said guide-rod and water-channels provided in the walls of said cylinder and extending above and below the limit of the upstroke of said valve to provide a cross-sectional area around the edge of the valve for the free flow of water passing through the unobstructed inlet-opening.

3. In a pump-bucket, the combination with the cylinder having a water-chamber provided with unobstructed inlet and discharge openings, of a valve fitting said chamber and adapted to close said inletopening, said valve slidable vertically within the chamber above said opening, vertical Water-channels provided in the walls of said chamber to form a cross-sectional area for the free flow of water past the edge of the valve and extending above and below the limit of the upstroke of said valve, an annular groove provided in the outer surface of said cylinder, sectional packing-rings fitting closely therein, and ports leading from the water-channels into said annular groove above the limit of the upstroke of said valve.

4. A pump piston or bucket comprising a hollow cylinder 2, having an unobstructed water-inlet opening 4: in its lower end and open at the top, said cylinder having a reduced threaded end,'in combination with the threaded ring 16 fitting said reduced end and having its outer periphery flush with the surface of the cylinder, a yoke 17 integral with said ring 16, a guide and attachment rod 9, secured in said yoke and concentric with said cylinder, the valve 7 normally seated in said opening 4 and smaller than the inner diameter of said cylinder, said valve having the sleeve telescoping upon the lower end of said rod 9, vertical water-channels provided in the inner wall of said cylinder, said cylinder having a packing-groove, and a suitable packing provided therein, substantially as described.

In witness whereof I have hereunto set my hand this 27th day of August, 1900.
